Saturn is really about perfection, convention, hard work. You can really crystalize every area of your life with Saturn he's not a bad guy, he's more like a tough parent. However hard aspects can bring about a lot of pressure in both finances and love but with Venus really all relationships.
Saturn doesn't make things easy, instead he makes it harder. He wants you to be wise, work hard and have standards. However, he tends to take the beauty out of things because it's usually time to get real. Venus is all things that bring pleasure such as sensuality, love and money. When Saturn begins to make a hard aspect with Venus in your natal chart, you may not notice it initially but your view changes to a more somber perspective. This can be a result of money slowing down, or seeing the real colors of other people. If your relationship was not equal or good for you, you will now see it clearer than ever. In all truth though this transit can make you overbearing, nitpicky, critical, unhappy and impossible to be around and you might not even notice it yourself but others will.
If you are in a relationship prior to this transit chances are you will unconsciously or consciously push your relationship right out the door, whether it's to test the love of your partner or because you feel too much pressure or you are just seeing things negatively. It's important to wait to see how you feel after the transit if possible to avoid making a mistake. However, this is known as a break up transit and I have seen it more times than not be the case. Even if only temporarily. If you were unhappy prior to this transit, then you will really be unhappy during this transit and will likely want out and be actually willing to do so.
However, you must be aware that during this time, you are very irritable, negative and more than likely demanding.
On the positive if you have been overly accepting of bad treatment and need to get out of a dysfunctional relationship this transit will help you do it.
On a financial note, It is also known to slow down money, which most certainly contributes to one's overall frustration. Whether it's your partners money or your own, you are unable to fill your needs as lavishly as might have been used to prior to this transit.
This transit tests your relationships which actually is a very good thing, but not if you are being unreasonable during this time. If you decide to cool down a bit that's fine just watch for the tendency to push your relationship right out the door if that's not what you really want.
If you manage well you will both pull through and probably grow even stronger. If the relationship is based on any illusions, those will clear away, but also so will much of the good Saturn has a way of making things feel dull.
During this transit, I felt as if the walls were closing in around me. I began to feel suffocated and I lost interest in the things that I use to find pleasurable and began to find fault in everything. Yes, everyone is different but I have seen much of the same with others experiencing this transit as well.
As far as relationships, Saturn most certainly tests the strength and you have to really be in it for all the right reasons to make it.
The key is to realize that this transit serves to test the validity of your relationship(s), but also that you are testing your relationships. Think things through or take a break before making any rash decisions, there is a possibility that you can destroy a perfectly viable relationship as a result of your cold and extreme behavior change, irritability and irrational demands.
Yes, this transit can be brutal and a very difficult one but awareness always makes a difference.
